Question about BitmapButton

[DaiyaO]

Hello,

I just start learning wxWidget.I tried creating buttons with the same event handler and used this code to change the image of the buttons.

Code: Select all

EVT_BUTTON(4010, BoardWindow::Response)


void BoardWindow::Response(wxCommandEvent & event)
{
	wxBitmapButton *temp = (wxBitmapButton*)event.GetEventObject();
	temp->SetBitmap(*newimage);
}

It only works when i clicked the first created buttons and changed the image as i move my mouse to the other button.

Is there any fixes to this?

Many thanks and greetings

Hi,
Which OS/toolkit?
Which wx version?

Do you mean you click the button then move the mouse to the next button and then the bitmap is changed? It is not changed immediately when the button is clicked?

Thank you.

To make sure that the event object really is a wxBitmapbutton, use code like this:

Code: Select all

 wxBitmapButton *temp = wxDynamicCast( event.GetEventObject(), wxBitmapButton );
 if( temp )
 {  
  temp->SetBitmap(*newimage);
  temp->Refresh();
 }

Also, you may need to call Refresh() to make the new bitmap appear.

How do you connect the event to the other buttons? Do you have multiple entries in the event table? Or do you create all buttons with the same ID? The second version would be the wrong way to do it.
